This study examined the relationship of academic achievement to time perspective (future, present) and school membership (belonging, acceptance, rejection) among 232 low-income, urban African American adolescents. Findings indicated positive, significant relationships among academic achievement, future time perspective, school belonging, and school acceptance. A negative, significant relationship was found between academic achievement and present time perspective. Based on multiple regression analysis, the ability of time perspective and school membership to predict academic achievement differed across gender. Whereas present time perspective was predictive of academic achievement among males, school acceptance and future time perspective emerged as significant predictors of academic achievement among females. Present time perspective contributed negatively to academic achievement among males, while school acceptance and future time perspective contributed positively to academic achievement among females.
